<P>PROBLEM TO BE SOLVED: To provide a screen device capable of achieving a quiet winding of a screen fabric by eliminating irregular winding sound when winding up the screen fabric in a manual type screen device incorporating a coil spring. <P>SOLUTION: The manual type screen device includes a coil spring 2 interposed between winding rollers 10, which winds or feeds a screen fabric 11 so as to lift/lower the screen fabric 11, and a rotation supporting shaft 6A thereof and rotatingly energizing the screen fabric 11 feeding the winding roller 10 downward in the wind-up direction by an elastic restoring force. The screen device further includes a connecting member 3, engaged in the rotating direction so as to be rotatingly integrated with an internal peripheral face 10c of the winding roller, at one end side of the coil spring 2 so as to move axially with respect to the winding roller 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
